Box UI Elements are pre-built UI components that allow developers to add features of the main Box web application into their own applications. Use Box UI Elements to navigate through, upload, preview, and select content stored on Box. Box UI Elements are available as React components and framework-agnostic JavaScript libraries.

Please note that the demo page has limited functionality.


yarn add box-ui-elements or npm install box-ui-elements

To prevent library duplication, the UI Elements require certain peer dependencies to be installed manually. For a list of required peer dependencies, see package.json.


This documentation describes how to use UI Elements in a React application using webpack. If instead you require a framework-agnostic solution, please refer to our developer documentation. You can also reference our Elements Demo App and Preview Demo App for examples of minimal React applications using ContentExplorer and ContentPreview, respectively.



* These components utilize code splitting. See the Code Splitting section for more information.

Code Splitting

Code splitting is currently supported for some UI Elements. In order to use an Element with code splitting, you need to set it up in webpack.


Box UI Elements use SCSS stylesheets. Each of the Elements include their corresponding SCSS stylesheet to render properly. Once you import an Element within your React app, the corresponding stylesheet will automatically get included. However, you will need to setup webpack to handle .scss files by using the sass-loader / css-loader. This will direct webpack to properly include our SCSS files in your final CSS output. A sample configuration is shown here under the rules section.

Browser Support

  • Desktop Chrome, Firefox, Safari, Edge (latest 2 versions)
  • Mobile Chrome and Safari

Supported Packages

  • React 17: Box UI Elements currently supports usage in React 17 environments. Developers implementing UI Elements in React 18 may experience unexpected issues.
